Except for one thing:  Everything that the Cisco 675 does, Linux
does better.  And it does more.  And it has a modicum of security,
which the 675 has none of.

Its one thing to use a real Cisco in a real network situation, but 
even then you back up the router with a dual homed machine to 
perform more sophisticated/auditable functions than you can with
a router.

And just in case anyone isn't getting the point:  when you hook
everything up through the router all of your hosts are now on
the internet, with no effective firewall.  Keep that in mind.
